|
void panAboutViewCenter ( real angle , vector3d axis ) |
Adjusts the camera pan about view center by angle in degrees on axis .
Adjusts the camera pan about view center by angle in degrees.
|
quaternion panRotation ( real angle ) |
Returns the calculated pan rotation in relation to the angle in degrees taken in to adjust the camera's pan or left/right rotation on the Y axis.
Adjusts the camera roll by angle in degrees.
Adjusts the camera roll about view center by angle in degrees.
|
quaternion rollRotation ( real angle ) |
Returns the calculated roll rotation in relation to the angle in degrees taken in to adjust the camera's roll or lean left/right rotation on the Z axis.
|
void rotate ( quaternion q ) |
Rotates the camera with the use of a Quaternion in q .
